What causes angina?

Causes of angina. Angina is due to a narrowing of the coronary arteries - the vessels that supply the heart with blood. These arteries become furred up with fatty deposits, a process called atherosclerosis, leading to coronary heart disease.

As well as atherosclerosis, other rarer problems can also lead to angina, including:
• heart valve disease
• anaemia (a reduced amount of red blood cells in your blood)
• fast, abnormal heart rhythms
• diseases of the heart muscle
• a spasm or cramping of coronary arteries (see Variant angina)

Coronary heart disease, which is the main cause of angina, is more common in men than women. The likelihood of getting it increases as you get older. You are also more prone to getting coronary heart disease if you:
• have a high blood cholesterol level
• have high blood pressure
• have diabetes
• smoke
• do little physical activity

Angina can sometimes run in the family, so if a close relative has had angina, your risk of having it may be higher.

Circulation. Angina is caused by inadequate circulation and oxygen to the muscles of the heart. Can be caused by arterial blockage or arterial spasm. Activity can sometimes cause the heart to need more blood supply than can be provided resulting in episodes.

Angina pectoralis. Angina is caused when blood flow to an area of the heart is decreased, impairing the delivery of oxygen and vital nutrients to the heart muscle cells. When this happens, the heart muscle must use alternative, less efficient forms of fuel so that it can perform its function of pumping blood to the body. The byproduct of using this less efficient fuel is a compound called lactic acid that builds up . Read more...
